Henry Grey, 1st Earl of Stamford (c. 1599 – 21 August 1673), known as the Lord Grey of Groby from 1614 to 1628, was an English nobleman and military leader. He was the eldest son of Sir John Grey and Elizabeth Nevill. His mother was probably a daughter of Edward Nevill, 8th Baron Bergavenny (died 1622) and his wife Rachel Lennard.
